Title: Automatic positioning system and method
IPC: H01L21/68
Filed: 1975-05-30
Abstract: 1509574 Positioning control system WESTERN ELECTRIC CO Inc 30 May 1975 [31 May 1974] 23675/75 Heading G3N An electrical positioning system is used e.g. in bonding a semi-conductor chip to a substrate or aligning semi-conductor wafers or thin film substrates to photoresist masks. Wheels 45 and 46 index a compliant tape window under the bonding tip of bonding head 44. Light passes from source 49 via prism 48 to the window whence it is reflected via the prism to microscope 42 and vidicon 41. The microscopic window image is converted to electric signals and these pass to auto alignment control 35 having a pattern generator, Fig. 2, (not shown) which generates signals representing a video image of a pattern of reference zones. These are compared with the vidicon signals, Figs. 3A-E, (not shown) and a motor control aligns the reference signals with the vidicon signals. Then light from source 49 is interrupted and light from source 50 passes via the prism to illuminate one of semi-conductor chips 23 on stage 21 whence it is reflected via the prism to the vidicon 41 and system 35. The chip image is compared with the reference and motor control 30 moves the chip until it is aligned with the reference. Thus the chip is now aligned with the window. Prism 48 is then removed and the bonding head 44 is lowered to pick up the chip on to the window using vacuum pressure. The bonding head 44 is returned to its original position, the prism is returned and the reference zones realigned using light source 49. Then chip stage 21 is moved and replaced by stage 24 carrying the substrate 26. Light from source 51 illuminates substrate 26 and is reflected through prism 48 to the vidicon. The image is compared with the reference as before to align the substrate and chip. Bonding is then effected by removing the prism and lowering the head to contact the chip, force or heat being used to complete bonding. The same procedure is then effected for the succeeding chips. In a second embodiment, Fig. 11, (not shown) a semi-conductor wafer is movable in X, Y and rotary directions for alignment with the photoresist mask using a vidicon arrangement as described above.

Title: Improvements in or relating to self-acting spinning mules
IPC: D01H3/24
Filed: 1926-09-29
Abstract: 268,230. Hunter, E. Sept. 29, 1926. Mules.-Means is provided to defleet the winding-chain and vary its effective length during the movement of the carriage relatively to slow down the speed of the spindles as the down coils are being wound, so that fewer and steeper down coils are wound. The winding-chain 4, 5, Fig. 1, has attached to it a chain 10 secured to a strap 8 on the winding arm 1. The strap 8 is adjustable but is arranged to keep a constant distance from the strap 6 in all their positions along the arm 1. At the commencement of the inward run the chain 10 deflects the winding-chain and gradually allows it to straighten and to increase in effective length slowing down the spindles. When the down coils have been laid the arrangement is such that the winding-chain is straight and the chain 10 is slack. The auxiliary chain may be arranged below the winding-chain in which case the winding speed of the tin-roller must be adjusted for a normal speed for the up coils. The winding-chain may be deflected by a horn 17, Fig. 4, on the strap 16 to which the winding-chain 15 is attached. A link with pivotal joints to allow it to bend may replace the auxiliary chain.

Title: Improvements in or relating to brake assemblies for power-driven vehicles
IPC: F16D65/28
Filed: 1951-04-09
Abstract: 714,315. Endless track vehicle brakes. INTERNATIONAL HARVESTER CO. April 9, 1951 [April 19, 1950], No. 24329/52. Divided out of 714,253 [Group XXXI]. Class 103(1) The invention relates to a construction of brake mechanism in a vehicle having endless tracks or other ground engaging driving units at its sides, each of which is driven independently through variable ratio drive means selectively operable for applying braking force alternatively to' braking elements for establishing the drive to a driven shaft at high or low ratio, and having also independently operable braking means for each driven shaft. The invention is shown as applied to the transmission system for an endless track which is more fully described in Specification 714,253. As shown diagrammatically in Fig. 1 and in Fig. 2, the endless tracks 15, 16 are driven from a drive shaft 19 through a gear box indicated generally at 23. Between the gearbox and each track are disposed three brake discs marked L, H and B. The brake disc B acts directly on its respective shaft to brake the adjacent track member and may be applied by a driver's pedal 69 operatively connected through linkage 102, 100, 91, 98 and 98<SP>1</SP>. The brake disc B may also be applied by a hydraulic ram 71 acting through an arm, supply of fluid to the ram being under control by manually operated means. The discs H and L are coupled by shafting coaxial with the track driving shaft 18 with gearing members within the transmission housing wherein by braking the discs relatively high and low speeds are applied to the respective track members. The application of the brake blocks to the discs H or L is by means of a pivoted yoke member 52, Figs. 2, 5, and 6, moved one way or the other by a double piston hydraulic ram 110 energizable by a selective manual control for putting into operation neutral, slow or high speed transmission ratios. The brake blocks 29a, that engage the shaft brake disc B are pivoted to the yoke member 32 on pins 51, the yoke member 32 being itself pivoted in a frame member 35 by pins 36. Similarly friction blocks 58 and 59 for engaging the low and high speed transmission brake discs are pivoted to the yoke member 52 by pins 56 and 57, the yoke member 52 being itself pivoted to the frame 34 by pins 53 and 54. The force on the discs H and L is resisted by fixed blocks 61 and 62. As shown in Fig. 2, the yoke member 52 is applied by ram 110 towards the disc L by compression of a spring unit 112a, the adjustment of the yoke member being possible by rotation of the threaded member 115a. The yoke member 32 may be adjusted similarly by rotation of the member 87a.

Abstract: 938,875. Air filters. VOKES Ltd. June 18, 1962 [July 5, 1961], No. 24351/61. Class 8(2). The periphery of the feed spool 3, Fig. 2, of an intermittently traversed band filter having a time-controlled motor driven rewind spool (not shown) supports the free end of a pivoted arm 1 which when the feed spool 3 is empty assumes a position wherein it closes a switch 4 in an alarm circuit. The alarm may comprise a bell 16, Fig. 3, and/or a lamp 15. The arm 1 carries a wheel 2 bearing on the spool surface and a cam 5 geared to the wheel and rotated thereby. The cam operates a switch 6 which in conjunction with the motor timer and a delay device neither of which are shown controls the motor 7 driving the rewind spool. In addition to switches 4, 6 the circuit includes a timer operated switch 11, a manual switch 12 and a switch 10 operated by a relay 13 and during stationary periods assume the positions shown. When the timer closes switch 11, relay 13 is energized and closes switch 10 to start the motor 7 and the delay device in the timer is such as to allow time for the lobe of cam 5 to close switch 6 before the timer-controlled switch 11 becomes closed thereby allowing continued rotation of the motor 7 until such time as the cam 5 closes switch 6. The motor control device becomes inoperative when switch 4 is moved to its reverse position shown in the broken line, i.e. when the supply spool is empty.
